Plugin Slows Vanilla to a Crawl

I'm currently using Vanilla 2.1.7 with the latest version of the Sphinx Search plugin. I've installed and configured everything, but while the plugin is enabled my page load times are ridiculously slow (>1 minute per). Any idea on where to start fixing this?

I haven't tested this with the version of vanilla you are using. I think I just got it working on v2.0 last year, so the plugin could be the cause of the problem - but I'm not sure where and how it would timeout.

Here's the item right before everything goes to pot, and the item that causes the lag, according to the Vanilla Debug plugin. The preceeding 4 queries for this dashboard page all took less than 0.02 seconds.

I'd say it has something to do with the fact that Sphinx can't tell searchd is running, or possibly some misconfiguration along the way. Thanks for verifying that it does work well with 2.1.7, though. It's the last thing stopping me from turning off our olf vBulletin forum and moving totally over to Vanilla.

Yea - I can see the notifications. I'm sort of confused as to what your pastbin contains. It looks like it took 120s to load (btw, wouldn't your PHP engine issue a timeout by this time?) and then the vanilla debug printout out its configuration file?

OK, all done. Works perfectly now. My issue was that, with the version of Sphinx I was using, I had to change to port definition. The documentation I was reading said that the appropriate definition was "9312:mysql41", however, that opens port 9312 for SphinxQL and not the Sphinx API. Removing :mysql41 addressed the issue.
